It's not a request, it's a warning. The machine will be without power soon, and it's up to the machine whether it wants to prepare for that or not
I had a systemd bug delay shutdown for 2 mins every time for a very long time on Debian. Never managed to fix it, Fedora did not have the same issue fortunately.

Ah yes, tinkering with the registry. There's that user friendliness Windows is famous for.

Nah man. "kill" doesn't shut the system down quickly. This is the "instant death" way - the kernel reset gun - no shutdown scripts, no disk sync, just reset to BIOS boot sequence, instantly:
As root:
echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger
If you change out the "b" in the second command for "o" it will just halt the kernel instead of rebooting. Still switched on, but the system is doing absolutely nothing.
I used to use this trick all the time to test high availability server clusters.

Three whole seconds? Ain't nobody got time for that shit
echo b > /proc/sysrq-trigger
I prefer Windows giving programs time to shut down properly. You can always click on 'shutdown anyways' or whatever the button is called. Also what kind of programs do you run that take 45 seconds to shut down?
That's actually the default on Linux as well. This meme just gets shared every other week, perpetuating the myth. OP seems to be aware of that.
It doesn't "give time" it just waits indefinitely, and if the program doesn't terminate your laptop will just sit there until the battery dies. This has to be one of the dumbest aspect of Windows, and god knows there are many
Getting Amos vibes...

Meanwile MorphOS booting up and shutting down:

The jingle at the start is the Mac's own. The shutdown is so fast, you'll miss it if you blink. No services, no demons or whatever.
(That was 2013. I'd argue it starts up even faster now.)
